Node-to-Node (Online) - The Node-to-Node test verifies communications
between the port and its device node or device loop. The port being tested
must be online and connected to a remote device. The port passes the test if
the frame that was sent by the ASIC matches the frame that was received.
This test does not disrupt communication on the selected port. This test
requires that the port be online, and therefore, does not disrupt
communication.
To run the internal, external, or online port loopback test on a port, do the
following:
1. In the faceplate display, select the port to be tested.
2. Open the Port menu and select Port Loopback Test to open the Port
Loopback Test dialog.
3. In the Test Selection area, choose the radio button for the type of loopback
test to be run (Internal, External, or Online). If you choose the internal or
external test, SANbox Manager will prompt you to confirm that the port state
needs to be changed to the diagnostic state. Choose the OK button and
SANbox Manager will change the port state.
4. Enter the frame count, frame size, and choose a test pattern radio button.
You may use the default pattern or enter an 8-digit pattern (hex). For online
test, you can select the Terminate Test Upon Error check box if you want
the test to stop should it encounter an error.
5. Choose the Start Test button to begin the test. The Test Results area
displays the test status, number of frames sent, and number of errors found.
6. To test another port, open the Select Port pull-down menu and select
another port (number) and test type (Internal, External, or Online) in the Test
Selection area.
7. Choose the Start Test button to begin the next test. Observe the results in
the Test Results area.
